• cheat sheet

Prestart

• Install Java 8 JDK
• Install Docker and Docker Compose
• Install Intellij Idea

Run Kafka, Elassandra, Prometheus and Grafana

Start containers(required)

For mac:

cd dev-environment
docker-compose -f env-mac.yml up -d

For linux family:

cd dev-environment
docker-compose -f env.yml up -d

Run chain node (only for pumps)

In order to fetch data from chains pumps need chain node to interact with. To run chain node locally using docker use following commands:

1. Parity for Ethereum

sudo  docker run -d -p 8545:8545 --name parity_eth \
-v ${REPLACE_IT_BY_HOST_FOLDER}:/cyberdata parity/parity:stable \
--db-path /cyberdata --jsonrpc-hosts all --jsonrpc-interface all --jsonrpc-threads 4

2. Bitcoind for Bitcoin

docker run -d -p 8332:8332 --name bitcoind --restart always \
-v ${REPLACE_IT_BY_HOST_FOLDER}:/home/bitcoin/.bitcoin ruimarinho/bitcoin-core:0.15.1 \
-server -rest -txindex -rpcpassword=cyber -rpcuser=cyber -rpcallowip=0.0.0.0/0

Or you could use any public available node (with appropriate settings) by passing CHAIN_NODE_URL environment variable to pump. For example CHAIN_NODE_URL=http://127.0.0.1:8545.

Import project to Intellij Idea

Open Project in idea by selecting: Import Project -> selecting build.gradle file from the repository root Wait for dependency downloading and indexation

Run Ethereum Pump from intellij Idea

Go to EthereumPumpApplication.kt and press green triangle on left to the code (on example line 14):

Pump will fail due to lack of CHAIN_FAMILY environment property, let's define it: Select "Edit Configuration"

Add properties:

Now, run pump one more time, it should start.
